soc/intel/skylake: Add Kconfig option to select UART index
Skylake/Kabylake SOC has two possible ways to make serial
console functional.
1. Legacy IO based access using Port 0x3F8.
2. LPSS UART PCI based access.
This patch to provide option to select index for LPSS
UART port: 0 = LPSS UART0, 1 = LPSS UART1, 2 = LPSS UART2
PCI based LPSS UART2 is by default enabled for Chrome Design.
